Hey guys...…….I got my car back . I need a stock upper control arm for the right side. Am I correct in fitment that a 78-87 gbody front arms are the same? One listing on Ebay indicates arms from an S10 Blazer will fit? Anybody know? Thanks! I'll post some pictures soon.

Yes any 2wd S chassis are the same. all g bodies are the same.

I cant give those things away when I have them, maybe inquire with some local circle track racers most sanctions allow tubular uppers.

Good time to slap some tall upper ball joints on too.

Any idea if the stock uppers can take a taller ball joint when lowers also have a .5 taller ball joint? Gotten mixed feedback on this.

You need long upper control arm mounting bolts.

To get the camber and caster back, it could take additional shims.
Oh, okay. Phew! Because when I installed those BJs (upper and lower) in the wagon the shim stack was already maxed out - like the UCA is just millimeters off of my $1000 headers. The only way I am gaining more camber/caster is longer bolts, aftermarket UCAs with tiny bushings and offset shafts.
